While comparing Cubic Zirconia and Nickeline physical properties, the important data you should know is its chemical composition. Since chemical formula defines the molecular structure of the crystal, most of the physical properties like color, tenacity, solubility are governed by Cubic Zirconia and Nickeline chemical formula.
Another important criteria for qualitative analysis of gemstones is Cubic Zirconia and Nickeline Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Cubic Zirconia and Nickeline Optical Properties during the identification of gemstone. Specific gravity of Cubic Zirconia is Not Available whereas that of Nickeline is Not Available.
